![]() ![]() Only later Fortran offers the addendum feature, but the Tab feature is much older.Īnother approach would be to write forth a literal "0000" instead of the integer, but this is less flexible. It does not overwrite the subsequent ".125", and as no further output items appear the deed is done. 5 addendum to I5 meaning print leading zeroes rather than leading spaces. ![]() This would need adjustment for other sizes, but works as follows: The value part is printed (in the format system's working area) as "bbbb7.125" (b's standing for spaces), then the T1 moves the finger back to column one, and the I5.5 writes out "00007", the. ![]() INTEGER IV REAL V DATA V / 7.125 / !A positive number. HOLD \ HOLD inserts a character into the number stringĪt the console we can input a double number, execute the format routine and type the resulting string.ħ.125 0000#.# TYPE 000007.125 ok Fortran To replicate the example for this task we could write: We are also free to create a mnemonic name that gives a reminder at how numbers will appear. Typical of Forth the using the formatting routines means putting things in reverse order. The number is created in a "hold' buffer the output is typically a Forth style stack-string consisting of an address and a length. This small set of seven routines ( >DIGIT #S HOLD SIGN ) allow arbitrary number formatting of double precision and single precision numbers. Type: 123 s>d 8 ud.0 Result: 00000123 ok Type: -123 s>d 8 d.0 Result: -00000123 ok Detail įorth's number formatting words are different than many other languages because they are active code rather than using a pattern string. printf ( "%%09.3f%N", > ) end end Elixir In this example, the line would be: - printf ("%%09.3f%N", v) - The more deliberate form is used in the actual example, - as it is more representative of common usage, when there - are multiple value arguments. When only one argument is needed, then there is also the - option to use just the value, without the container. ![]() Use the AEL_PRINTF class from the Amalasoft Eiffel Library - freely available from do - printf accepts a format string and an argument list - The argument list is a container (often a manifest - array) of values corresponding to the type of the format - specified in the format string argument. formatted ( v ) + "%N" ) end -|- print_formatted_ael ( v : REAL_64 ) - Print the value 'v' as a zero-padded string in a fixed - overall width of 9 places and, with a precision of - to 3 places to the right of the decimal point. Use the FORMAT_DOUBLE class from the standard library local fmt : FORMAT_DOUBLE do create fmt. do print_formatted_std ( 7.125 ) print_formatted_ael ( 7.125 ) end -|- print_formatted_std ( v : REAL_64 ) - Print the value 'v' as a zero-padded string in a fixed - overall width of 9 places and, with a precision of - to 3 places to the right of the decimal point. */ define p (n, c ) - Initialization make - Run application. * * Use an assignment, as t = p(1.5, 1), to discard the return value * from this function so that bc not prints the return value.
